Is there a way to compare the length of the array returned after an API refresh call with the previous value?
For instance:
let currentLength;
let previousLength;
ngOnInit() {
this.dataService.getData().subscribe(data => {
this.data = data;
this.currentLength = this.data.length;
// Add logic here to compare currentLength with previousLength
})
this.dataService.getUpdatedData().subscribe();
}
if (this.previousLength !== this.currentLength) {
// Insert your custom code here
this.previousLength = this.currentLength;
}
During component initialization, previousLength starts as undefined which triggers the condition to be true
It is within this initial condition that we assign a value to previousLength
Subsequently, the condition will operate according to your specific requirements
